To all whom t may concern:

Be it known that LFERDINAND IMHoRs'r,

of the city of Baltimore, county of Baltimore,

and State of Maryland, have invented nev.`

\ is a specification.

i tors as built within a vessel struct such' improvements in The nature of my improvements, taken in connection with the drawings, will enable any one skilled in the art to comprehend and conmachinery in freighting-vessels.

. My invention relates to a iiexible cover and the necessary fastenin gs of chains and pulleys,

for the purpose of holding the cargo in its `place and preventing the shiftin g of the cargo.

Figure l shows a vertical longitudinal section of the compartments of a vessel with stationary elevators, also shaftings and cogged wheels orpulleys for working elevators proper, also the iiexible` covcrwith ribs, ropes or chains, and pulley-blocks arranged for holding the cargo. Fig. `2 shows a horizontal section and plan of the same. Fig. 3 shows a vertical cross-section of stationary1 elevator as built within a vessel, showing the cogged wheels as arranged for transmiting motion from the main driving-shaft to the elevators proper. Fig. 4 shows a plan view of the elevator. Fig. 5 shows a Vertical section of the elevator.

In Figs. 1, 2,. 3, A shows permanent elevaor compartment,

b. The main shaft E, with cogged wheels V,

upon correspondis constructed to operate this manner a cargo of grain, ore, coal, ory

other merchandise can be moved from the vessel in a very short time.

. Figs. l and 2show my attachment forholding the cargo securely after the vessel is loaded. It consists of a flexible covering, g, made of canvas or other durable material. Fastened to this covering at short distances are rmly secured ribs K K, ot' solid material, as wood or the like. This covering is securely fastened by a series of bolts and rings to the sides of the vessel, so that each section may be lapped over its neighbor after the cargo is in. covering is then drawn down iirmly over the cargo by means of a series of ropes and pulleys, h h, so rigged that they may be easily fastened as the cargo settles.

What I claim as new, and desire to have secured to me, is y The iiexible cargo-cover g, having the distributed ribs K K, in combination with an ap- This paratus, h, consisting of a series of ropes or chains and pulley-blocks, arranged for 'drawing the cover tightly over the cargo,substan tially as described.
